Hang on, though: doesn't this essentially hand Apple a big list of which domains you communicate with and how frequently? There's also nothing stopping them reading the emails on the way through. I know a lot of people trust Apple more than Google, but you're essentially signing up for a vendor-locked product that you're hoping Apple will continue to support, with no guarantee they won't collect - even at an aggregate level - your communication preferences.
They're even slightly pre-filtered for Apple's convenience, as the times you're likely to use Hide My Email are for shopping and social media - nice, ripe marketing targets.
